I've seen a couple questions around here like How to debug RESTful services , which mentions:

In Firefox 3, the answer is 6 per domain: as soon as a 7th XmlHttpRequest (on any tab) to the same domain is fired, it is queued until one of the other 6 finish.

Scroll down for the getById.getByClassName vs. qSA comparison! If we wanted to select all elements of class "bar" which are inside the element with the ID "foo" , we could write this:

I want to provide my visitors the ability to see images in high quality, is there any way I can detect the window size (or better yet, the viewport size - see green area ) of the browser with Javascript? Source: Tips4all

I was thinking about this today and I realized I don't have a clear picture here. Here are some statements I think to be true (please correct me if I'm wrong): the DOM is a collection of interfaces specified by W3C. when parsing HTML source code, the browser creates a DOM tree which has nodes that implement DOM interfaces. the ECMAScript spec has no reference of browser host objects (DOM, BOM, HTML5 APIs etc.). how the DOM is actually implemented depends on browser internals and is probably different among most of them. modern JS interpreters use JIT to improve the code performance and translate it to bytecode I am curious about what happens behind the scenes when I call document.getElementById('foo') . Does the call get delegated to browser native code by the interpreter or does the browser have JS implementations of all host objects? Do you know about any optimizations they do in regard to this? I read this overview of browser internals b

I have a website (Flash) localized into a dozen of languages and I want to auto-define a default value depending on the user's browser settings in order to minimize the steps to access the content. FYI, I cannot use server-scripts due to proxy restrictions, so I guess JavaScript or ActionScript would be appropriate to solve the problem. Questions: What would be the best method to 'guess' the user's locale ? Are there any existing simple classes/functions that could help me out (no complex localization bundles) ? Specially to break down all the possible languages into a smaller number (the translations I have) on a smart way . To which point can I trust such a solution ? Any other workarounds or suggestions ? Thanks in advance! Source: Tips4all

So I want to create an Android app so it would be registered somewhere in android OS (or just would start on system start) and when phone user clicks on special button on a web page inside a web browser a la: <a href="myapp://mysettings">Foo</a> my app would pop up and run using the params sent in that URL. So how do I do such thing? I need a tutorial with code! Source: Tips4all

It's quite difficult to find id's in page. F.e. it's much easier to work with picture and then get id from popup. I use Chrome but feel it can be much better and easier. My question is. Which browser is better for work with javascript? Any other tools?
